We describe an algorithm for estimating the radial component of the velocity of a sound source based on information about frequency shifts of the interference maxima of the field and consider the problem of its interference immunity. We obtain the limit estimate for the value of the input signal/noise ratio when the algorithm is working effectively. We present results of computational and field experiments...
We consider a method for estimating the depth of a sound source in a shallow water acoustic waveguide for a weak signal, based on information on the ratio of the amplitude of neighboring modes of the wave field. Results of a numerical experiment using a single receiver and a horizontal linear array in the lowfrequency region are given. We demonstrate the stability of the method to errors in measuring...
